Authorities have arrested the Connecticut father accused of murdering his wife, and then boarding a bus to Manhattan and abandoning his 5-year-old daughter at the Port Authority Bus Terminal, authorities said.

Ruono had been on the lam for nearly four days, hopping between various shelters across the city. He borrowed cellphones from several residents to make calls, which helped authorities track him down, the sources added.

Cops were tipped off to the child by concerned commuters who noticed her standing alone. The little girl was able to lead authorities back to her home, and that’s when cops discovered Runo’s slain wife.

Ruono is currently being held at a Manhattan precinct. He’s expected to be extradited back to Connecticut, sources said.
